Project management for cloud computing development

This article deals with the impact of employing cloud computing architectures in the field of software systems development. We analyze the individual influence of the cloud computing model characteristics on the project development process.

Cloud Migration: A Case Study of Migrating an Enterprise IT System to IaaS

This case study illustrates the potential benefits and risks associated with the migration of an IT system in the oil & gas industry from an in-house data center to Amazon EC2 from a broad variety of stakeholder perspectives across the enterprise, thus transcending the typical, yet narrow, financial and technical analysis offered by providers. Our results show that the system infrastructure in the case study would have cost 37% less over 5 years on EC2, and using cloud computing could have potentially eliminated 21% of the support calls for this system. These findings seem significant enough to call for a migration of the system to the cloud but our stakeholder impact analysis revealed that there are significant risks associated with this. Whilst the benefits of using the cloud are attractive, we argue that it is important that enterprise decision-makers consider the overall organizational implications of the changes brought about with cloud computing to avoid implementing local optimizations at the cost of organization-wide performance.Comment: Submitted to IEEE CLOUD 201

Decision Support Tools for Cloud Migration in the Enterprise

This paper describes two tools that aim to support decision making during the migration of IT systems to the cloud. The first is a modeling tool that produces cost estimates of using public IaaS clouds. The tool enables IT architects to model their applications, data and infrastructure requirements in addition to their computational resource usage patterns. The tool can be used to compare the cost of different cloud providers, deployment options and usage scenarios. The second tool is a spreadsheet that outlines the benefits and risks of using IaaS clouds from an enterprise perspective; this tool provides a starting point for risk assessment. Two case studies were used to evaluate the tools. The tools were useful as they informed decision makers about the costs, benefits and risks of using the cloud.Comment: To appear in IEEE CLOUD 201

The impact of blockchain technology on information technology governance

Abstract : This dissertation forms a hypothesis that Blockchain technology is giving rise to a new form of enterprise IT governance. Blockchain is a computational design that first emerged as the technology underpinning the popular cryptocurrency Bitcoin. Despite its use in cryptocurrency, it has an array of different use cases that may significantly impact the global economy. Some areas that Blockchain will affect were never truly re-engineered by the internet era, namely Economics and Governance. This dissertation is a qualitative exploration and analysis of blockchain’s impact on Information Technology Governance. The research unpacks these implications by comparing governance in hierarchical organisations and decentralised autonomous organisations. The primary data is attained through a questionnaire and the secondary data from a case study. The research contains two literature reviews on Blockchain and IT governance. The primary finding of this research reveals that although conventional IT Governance will still be used in the future, fifty percent of the sentiments shared by subject matter experts indicate that unconventional governance will take precedence with decentralised autonomous organisations. This implies that changes in traditional governance frameworks may be required in the future.M.Com. (Information Technology Management

Scottsdale Community College Provides their Students Open Access with End-to-End Virtualization

Due to shrinking budgets and new demands for technology, Scottsdale Community College (SCC) IT department needed an effective, sustainable solution that would provide ubiquitous access to technology for students, faculty, and staff, both on- and off-campus. This paper explores how SCC implemented a complete virtualized computing environment
